The diets had either no condensed tannin (CT), lucerne (Medicago sativa cv. Otaio), white clover (Trifolium repens cv. Tahora), or had ...
In this study wool characteristics of Libyan sheep in north-eastern Libya were investigated in a coastal region extended from El-Marj (32 25 N and 20 30 E) to Emsaad at the north-eastern border of the country (31 33N, 25 6 E). Twelve locations, one flock per flock were studied. Three sites have b...
